Audio CD players read their discs at a precise, constant rate (4.3218 Mbit/s of
raw physical data for 1.4112 Mbit/s (180.6 kB/s) of usable audio data) and thus
must vary the disc's rotational speed from 8 Hz(480 rpm) when reading at the
innermost edge, to 3.5 Hz (210 rpm) at the outer edge.
480 rpm = 2,880 degrees per second
210 rpm = 1,260 degrees per second

With what kind of constant velocity the disc rotates at a constant speed?
"Some later CD drives use CLV technology in combination with constant angular velocity (CAV). With CAV, the disc rotates at a constant speed, just as is done with hard drives."(pg 459, A+ Guide to Managing and Maintaining Your PC)
Does the weight of a car affect its speed?
Top speed - No, Acceleration - yes top speed is all about areodynamics (frontal area, Cd "coefficient of drag"), horsepower and gearing. Acceleration is all about power to weight and traction upto about 100mph, above 100mph the areodynamics starts playing a more important roll.
How does air resistance change speed?
Air resistance acts in the opposite direction of an object's motion to reduce its speed. The force of air resistance or drag is given by the following formula:FD = 1/2 A CD ρ v2whereA is the projected area of the objectCD is the drag coefficientρ is the air densityv2 is the relative velocity of the air
How many grams would a CD player weigh?
a CD weights about 15 - 20 grams but a CD player weights about 15 kg
Do CDs have low friction?
If you are talking about a CD or CD ROM then yes. When I was in Middle School we had a project where we made balloon powerd cars. I made my car have CD wheels and it went far. CD's have a smooth wheel like structure. A wheel can help prevent friction, so the CD's circular shape enables it to have less friction.
Define constant angular velocity and explain how it is applies to a CD?
Angular velocity is the measure of angular displacement (in one or the opposite) direction over a unit period of time. In the context of CDs , one unit in which this can be measured is the number of revolutions per second. A constant angular velocity means that the CD is turning through the same angle each second.
Is there software that can be used to determine at what speed a CD was written?
yes, Nero CD-speed

What role does data on CD ROM play in determining the speed of a computer?
The CD ROM does not have any affect on the speed of the CPU or the speed of the Frontside Bus. The CPU and Frontside Bus is what carries data and the CD ROM is not connected nor involved with the speed of the computer.
Why is 2x and 24x printed on CD-roms?
The speed printed on a CD is the maximum speed it can be reliably written at. If you tried to get a PC to write at a speed of 24x using an 8x CD, the data more than likely will be corrupt.
What kind of speed rates are used for burning of a high quality CD?
The higher the speed does not necessarily translate to a higher quality CD. The higher the speed indicates the amount of time it will take to complete the transfer of music to the CD. 4x is a speed that will create a good quality.
How does constant angular velocity apply to CD standards?
If a stationary base reference line and a zero line on the disk both extend from the outer edge of the disk to the center of rotation, constant angular velocity will ensure the periodic angle changes between the two lines remains a constant. This allows the CD to be played smoothly.
What kind of velocity causes a disc to rotate at a constant speed?
Uniform-Pertaining to computers-"Some later CD drives use CLV technology in combination with constant angular velocity (CAV). With CAV, the disc rotates at a constant speed, just as is done with hard drives."(pg 459, A+ Guide to Managing and Maintaining Your PC)
Which CD and DVD drives have the quickest writing speed?
The CD or DVD drivers speed is measured by xX e.i 24X. The higher the burning X speed the faster it will burn
Does the protocol speed ladder come with a CD?
No.
How does CD ROM affect the speed of a computer?
Here is the actual question: Explain the role of each of the following in determining the speed of a computer: CD Rom
